As you can see, Skinner's skeleton is different. I used Apu's skeleton. What's interesting is if you use the character swap cheat in Level 5 and once you get Skinner, he'll look normal, but will walk/run like Apu does. This however is a change of Skinner's actual body skeletal rig position.
What do you all think?
Also I'm not bringing up skeletal rigs of new characters from scratch again, as I know that doesn't work.
